davidong3000 said:i know electrons have spin and charge which makes them the smallest magnet. protons also have spin and charge. does this mean they are magnets too with a north and south pole?
Precisely where are these poles in relation to the spin axis of the proton and electron?
The magnetic moment of the proton is in the same direction as its spin, so its N pole would be on top. The electron magnetic moment is oppositeto its spin direction because the electron is negatively charged.davidong3000 said:so if i was looking down on the axis of an electron/proton in such a way so that it appears to be spinning anti clockwise, would i be looking at the north or south pole?

Its top pole is a S pole.
Meir Achuz said:The north pole would be at the "top" of the earth.
By "top" I meant where the head of the arrow woud be in the right hand rule for rotation. (If fingers curl in direction of rotation, the vector omega is in the direction of the thumb.)
vanesch said:And actually the magnetic "pole" of the Earth on the north pole is ...
a magnetic south pole !
The second answer is yes.davidong3000 said:so Earth is like a giant electron then . xcept Earth is not - charged. both Earth and electrons have their s pole on top according to rh rule.
so exactly how many teslas are single electrons and protons spitting out? and do the magnetic fields of these charged particles loop back on themselves from top to bottom like on ordinary magnets?
Meir Achuz said:The second answer is yes.
The first answer is a bit messy to calculate, but I get that the B field at the proton in hydrogen due to the electron's magnetic moment is about
one million tesla.
I used the H atom just as an example for the B field a distance of 1/2 angstrom away from a lone electron. The B field would fall of like 1/r^3, so an electron's B field would be about 100,000 T 1 angstrom away.davidong3000 said:what if it didn't have an electron? say a lone proton or lone electron, what would the tesla reading be?
The spin of a proton is a fundamental property that describes its intrinsic angular momentum. It is quantized, meaning it can only have specific values, and is typically denoted as 1/2. This means that the spin of a proton can only be either up or down.
The spin of a proton is independent of its charge. While the charge of a proton is positive, its spin can be either up or down. This means that a proton with an up spin and a proton with a down spin will have the same charge. Spin and charge are two separate properties of a proton.
Yes, all protons have the same spin and charge. This is because protons are fundamental particles, meaning they cannot be broken down into smaller components. As such, they all have the same properties, including spin and charge.
The spin of a proton can be measured using a technique called nuclear magnetic resonance (NMR). This involves placing the proton in a strong magnetic field and observing the energy levels of the spin. The difference in energy levels can be used to determine the spin of the proton.
While protons have a magnetic moment due to their spin, they are not commonly used as magnets. This is because their magnetic moment is relatively weak compared to other materials, such as iron or neodymium. However, protons are essential in the creation of MRI machines, which use strong magnetic fields to image the body.
